Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

3.3K
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Secondary Lymphoid Organs

1.8K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

Inflammatory Bowel Disease I: Ulcerative Colitis

248
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Factors Influencing Drug Absorption: Disease States and Pharmacology

604
Multiple disease states can significantly influence the oral drug absorption process by affecting blood flow and the functionality of the gastrointestinal (GI) system. Various GI diseases, including conditions that alter GI motility, such as diarrhea, decreased acid secretions (achlorhydria), and infections, have been associated with reduced drug absorption.
Substances such as alcohol and specific drugs, including antineoplastics, can also negatively impact drug absorption. For instance,...

Physiology of Enteric Nervous System and Gut Health

343
The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...

Area of Science:

  • Gastroenterology
  • Immunology
  • Oncology

Background:

  • The intestinal barrier maintains homeostasis by controlling substance influx and is crucial for immune, microbial, and metabolic balance.
  • Disruptions in intestinal barrier function are increasingly linked to systemic diseases like non-alcoholic steatohepatitis and autism.
  • Hematologic and oncologic diseases frequently involve increased intestinal permeability due to treatments like antibiotics and chemoradiation, compounded by neutropenia.

Purpose of the Study:

  • To review the association between hematologic/oncologic diseases and intestinal barrier disruption.
  • To highlight complications arising from increased intestinal permeability in these patients.
  • To explore potential therapeutic strategies for modulating these complications.

Main Methods:

  • Review of existing literature on intestinal barrier structure and function.
  • Analysis of studies linking hematologic and oncologic diseases to intestinal barrier integrity.
  • Examination of therapeutic approaches for managing increased intestinal permeability.

Main Results:

  • Hematologic and oncologic diseases are significantly associated with compromised intestinal barrier function.
  • Increased intestinal permeability in these patients leads to various systemic complications.
  • The intestinal barrier presents a potential therapeutic target for mitigating disease progression and complications.

Conclusions:

  • Understanding intestinal barrier disruption is critical for managing patients with hematologic and oncologic diseases.
  • Targeting the intestinal barrier may offer novel therapeutic avenues to improve patient outcomes.
  • Further research into modulating intestinal barrier function holds promise for treating a range of systemic conditions.
